Encapsulated magnetically actuated vacuum interrupter with integral bushing connector

Abstract

Apparatus (10) for interrupting the flow of current in a power distribution system is disclosed for use with an enclosure containing insulating fluid. The apparatus (10) includes a housing (20) formed from insulating material and having a mounting flange (28) formed along the exterior of the housing (20). The flange (28) is located so that the housing extends away from the mounting side and the upper side of the flange. An electrical current interrupter (16), having electrical input and output ends (16a, 16b), is positioned in the housing (20) so that a portion lies within the portion of the housing extending away from the flange mounting side. An actuator (12) is mechanically connected to the interrupter (16) to provide the mechanical actuation required to interrupt the current flow between the input and output ends of the interrupter. When the flange (28) is attached to the enclosure, the portion of the housing (20) extending away from the flange mounting side extends into the fluid within the enclosure.
